--In the first half of the video, a woman follows fine thread, tangled and spread all over the floor, while untangling it and in the latter half, she lays new ribbon as she moves. The black thread in the first half symbolizes ruins of the past. When a point of the thread is lifted up, it catches on other multiple parts tangling and twining over it from diverse directions; it is not easy to carefully untangle it into order. The ribbon in the latter half symbolizes future. It is newly laid by moral, reason or constructive will. Newly placed ribbon will be worn out sometime and future will become past.
